It depends on the particular atom in question. Any of those subshells can make up the outer shells of atoms. Examples: In Mg, the outer shell is the 2s subshell. In P, the outer shell is the 3p subshell. In Fe, the outer shell is the 3d subshell, etc.
covalent bond
true
The outer shells of atoms can hold more electrons because they have higher energy levels compared to inner shells. These outer shell electrons are farther from the nucleus and experience weaker attraction forces, allowing them to occupy a larger electron capacity.
Atoms whose outer electron shells contain eight electrons tend to be stable and do not easily form ionic bonds in aqueous solutions. This is because they have reached the stable configuration known as the octet rule. In most cases, atoms that form ionic bonds have outer electron shells that are not fully filled with eight electrons.
Ionic bonds help fill the outer shells of atoms by transferring electrons from one atom to another. This results in the atoms achieving a stable electron configuration similar to a noble gas.
They are shared by the valence shells of the atoms involved in the bond.
More the number of shells in an atom, more away will be the electrons from the nucleus. Hence, weaker will be the attraction between nucleus and outermost electrons. So atom with more shells will let go their electrons easier than atoms with fewer shells.
they add or loose electrons from the outer most shells
Core electrons are located in the inner electron shells of an atom, closest to the nucleus. These electrons are tightly bound to the nucleus and are not typically involved in chemical reactions or bonding with other atoms.
They share electrons when they try and corm covalent or ionic bonds. This is because the atoms want to gain a full outer shell. So when they share electrons they can have full shells.
Electrons involved in bonding between atoms are valence electrons.
Electrons are the subatomic particles found outside the nucleus of an atom. These negatively charged particles occupy the electron shells surrounding the nucleus and are involved in chemical bonding with other atoms.
Atoms bond because they "share" their electrons. Every atom wants to have 2 atoms in their first shell, and then 8 in all the other shells. Lets say we have an atom with 3 electrons, and one with 9 electrons, they will esaly bond
covalent bond
Valence electrons form the bonds between atoms in a molecule.
true
A covalent bond is formed when sharing electrons.
